&lt;!-- TWO STEPS TO INSTALL TOP SPEED BY RPM:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Paste this code into the HEAD of your HTML document  --&gt;

&lt;HEAD&gt;

&lt;SCRIPT LANGUAGE="JavaScript"&gt;

&lt;!-- Begin
function calculate() {
var pi = 3.14159265359;
var radius = document.rpmForm.diameter.value / 2;
var circ = 2 * pi * radius;
var totlength = circ * .00001578;
var totrpm = document.rpmForm.rpm.value * 60;
var total = totrpm * totlength;
document.rpmForm.topSpeed.value = total;
}
//  End --&gt;
&lt;/script&gt;

&lt;/HEAD&gt;

&lt;!-- STEP TWO: Copy this code into the BODY of your HTML document  --&gt;

&lt;BODY&gt;

&lt;form name="rpmForm"&gt;
&lt;table border=0&gt;
